I had this problem about a month ago and deleted old kernels and it worked fine at that point. I had tried a few different flavors before I settled on Lubuntu so I thought that might be why I had the older kernel versions floating around. Here I am with the same problem again.

I'll admit that I am a relative noob on linux so the problem may be with the user! I am posting this information primarily to try and help. I'm going to delete the extra kernels again and see how it goes. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to initramfs-tools in Ubuntu. https://bugs.launchpad.net/bugs/798414 Title: update-initramfs should produce a more helpful error when there isn't enough free space Status in initramfs-tools: Confirmed Status in Ubuntu: Fix Released Status in initramfs-tools package in Ubuntu: Confirmed Bug description: Binary package hint: initramfs-tools When generating a new initramfs there is no check for available free space, subsequently its possible for update-initramfs to fail due to a lack of free space.
